This adds emissive ore textures to the Pixel Perfection Legacy Resource Pack
If you don't like certain textures being emissive for example coal ore then you can open up the resource pack and delete all mentions of that ore using the search bar. I personally remove coal ore as it can look brown when emissive with shaders turned on.
If you're using this with my Glowing Emissive Ores Resource Pack then make sure to put "Glowing Emissive Ores - Pixel Perfection Legacy" above it
As of my current knowledge, NeoForge doesn't have any native mods that add support for emissive textures.
As a work around you can use the following:
MoreMcmeta supports 1.16.5 and higher
Continuity only supports Emissive textures on version 1.18.2 or higher
MoreMcmeta supports 1.16.5 and higher
